Abstract
Chronic lower limb wounds are common. They can be of arterial or venous origin. In this article, we will present a clinical case of a 30-year-old patient with a chronic injury to the right medial malleolus. In his history, we can note a gunshot wound to the right leg. Ultrasonography and CT angiography helped in the diagnosis of traumatic arteriovenous fistula. The patient underwent a fistula embolization which allowed the wound to heal. The clinical presentation, additional examinations and the latest treatment recommendations will be discussed in this article.

Arteriovenous fistulas are abnormal connections between an artery and a vein

We present the case of a man who developed a chronic sore following venous insufficiency caused by an acquired traumatic arteriovenous fistula
Summary
Whilst some malformations arteriovenous are congenital, most are post-traumatic or iatrogenic. This renders the diagnosis even less easy in peaceful countries because of their scarcity. Diagnosis is difficult because of the large spectrum of clinical manifestations and sometimes late. These are pain, varicosity, swelling of a limb, thrill or audible bruit locally, diminished pulses distally and the downstream pressure is reduced [1]. When the arteriovenous fistula is large, there is ischemia claudication, steal syndrome and cardiac decompensation [2]. We present the case of a man who developed a chronic sore following venous insufficiency caused by an acquired traumatic arteriovenous fistula
